I just figured out the solution. If anyone else is having this problem, and is interested in the solution, this is it. You need to download this plugin, https://www.pbernert.com/gpupeteogl209.zip, and use it with your emulator. Then you will have to go to 'configure' and in the 'compatibility' area under 'Off-screen drawing' select 'extended can cause garbage' from the drop down menu. That should make all text display fine.
